Description

Die Erfindung betrifft einen hochpoligen geschirmten Kabelstecker mit einem aus zwei leitenden oder leitend ausgebildeten Teilen bestehenden Steckergehäuse, das an zwei einander gegenüberliegenden Seiten mit Schrägflächen ausgebildet ist und das mehrere Kontaktgehäuse aus Isoliermaterial enthält, welche eine Vielzahl von an Adern des Kabels angeschlossenen, mit Kontaktelementen eines Gegensteckverbinders verbindbaren Steckkontakten aufweisen.The invention relates to a multi-pin shielded cable connector with one made of two conductive or conductive Share existing connector housing that connects to two each other opposite sides is formed with inclined surfaces and which contains several contact housings made of insulating material, which have a large number of wires connected to the cable, connectable with contact elements of a mating connector Have plug contacts.

In vielen Bereichen, zum Beispiel in der Telekommunikationstechnik, erfolgt die Verkabelung statt an der Rückseite immer häufiger an der Frontseite eines Gerätes. Außerdem werden frontseitig immer mehr Signalleitungen benötigt, die mit hohen Bitraten betrieben werden. Es ist daher eine elektromagnetisch abgeschirmte Ausführung von Kabelsteckern erforderlich, das heißt zumindest eine Abschirmung des Kabelsteckers und der in ihm enthaltenen Kontakte nach außen, häufig aber auch eine Abschirmung von Kontakten oder Signalzweigen untereinander. Außerdem steht nach der europäischen Telekommunikationsnorm ETS 300 119-3 für Frontverkabelungen nur ein sehr beschränkter Raum zur Verfügung. So wird zum Beispiel für ein Gerät

Figure 00010001
600 x 600" ein Einbauraum inklusive Geräte- oder Baugruppenfrontplatte von 75 mm zugelassen, bei Geräten 600 x 300" beträgt der für eine Frontverkabelung vorgesehene Raum nur noch 40 mm inklusive Frontplatte. In many areas, for example in telecommunications technology, cabling is increasingly being carried out on the front of a device instead of on the back. In addition, more and more signal lines are required on the front that are operated at high bit rates. An electromagnetically shielded design of cable plugs is therefore necessary, that is to say at least one shielding of the cable plug and the contacts contained in it, but often also a shielding of contacts or signal branches from one another. In addition, according to the European telecommunications standard ETS 300 119-3, there is only a very limited space available for front cabling. For example, for a device
Figure 00010001
600 x 600 "an installation space including device or module front plate of 75 mm approved for devices 600 x 300 ", the space provided for front wiring is only 40 mm including the front panel.

Bisher wurden für Frontverkabelungen unter anderem Koaxialstecker, SUB-D-Stecker und metrische Stecker verwendet. Diese Stecker bieten jedoch im allgemeinen nicht die Möglichkeit, große Mengen von Signalleitungen bei geschirmter Ausführung und engen Einbaubedingungen an einer Frontseite eines Gerätes oder einer Baugruppe anzuschließen.So far, coaxial connectors have been used for front cabling, SUB-D connector and metric connector used. This However, plugs generally do not offer the possibility of large amounts of signal lines with shielded design and tight installation conditions on the front of a device or to connect an assembly.

Ein Kabelstecker der eingangs genannten Art ist aus der EP 0 421 373 A1 bekannt. Dieser Kabelstecker besitzt ein zweiteiliges leitendes Steckergehäuse, das mindestens zwei Kontaktgehäuse mit einer Vielzahl von Steckkontakten aufweist. Die Steckkontakte sind an Adern eines Kabels angeschlossen und als in Kontaktelemente eines Gegensteckverbinders einsteckbare Kontaktstifte ausgebildet. An der Steckseite ist das Steckergehäuse mit zwei seitlichen Laschen ausgebildet, die senkrecht zur Steckrichtung abragen, gegeneinander versetzt und mit einer Durchtrittsbohrung versehen sind. An der der Steckseite abgekehrten Seite besitzt das Steckergehäuse zwei einander gegenüberliegende und gegeneinander geneigte Schrägflächen, zwischen denen sich eine zur Steckseite parallele, flache hintere Stirnseite des Steckergehäuses befindet, an welcher die Kabeleinführung in Steckrichtung des Kabelsteckers erfolgt, das heißt das Kabel ist in Steckrichtung verlaufend zentral am Steckergehäuse angeschlossen. Der bekannte Kabelstecker ist somit in gerader Ausführung mit relativ hohen Seitenwänden ausgebildet und daher weniger für eine Frontverkabelung unter engen Einbaubedingungen geeignet.A cable connector of the type mentioned is from the EP 0 421 373 A1 is known. This cable connector has a two-part conductive connector housing, the at least two Has contact housing with a variety of plug contacts. The plug contacts are connected to the wires of a cable and as in contact elements of a mating connector insertable contact pins. On the mating side the connector housing is designed with two side tabs, that protrude perpendicular to the direction of insertion, against each other are offset and provided with a through hole. The connector housing has on the side facing away from the plug side two opposite and inclined Sloping surfaces, between which there is a mating side parallel, flat rear end of the connector housing is located, at which the cable entry in the direction of insertion Cable connector takes place, that is, the cable is in the direction of insertion running centrally connected to the connector housing. Of the known cable connector is therefore in a straight version with relative high side walls and therefore less for Front cabling is suitable under tight installation conditions.

Der Erfindung liegt vor allem die Aufgabe zugrunde, einen hochpoligen geschirmten Kabelstecker in einer für eine Frontverkabelung unter engen Einbaubedingungen geeigneten Weise auszubilden.The invention is primarily based on the object multi-pin shielded cable connector in one for front wiring suitable under tight installation conditions to train.

Diese Aufgabe wird bei einem Kabelstecker der eingangs genannten Art gemäß der Erfindung dadurch gelöst, daß die beiden einander gegenüberliegenden Gehäuseseiten im wesentlichen von den beiden dachartig zu einander angeordneten Schrägflächen gebildet sind und von einer Schrägfläche ein Anschlußstutzen abragt, daß das Kabel mit einem Ende, an welchem der Kabelschirm vom Kabelmantel befreit ist, soweit in den Anschlußstutzen eingeführt ist, daß ein Teilbereich des freigelegten Kabelschirmes aus dem Anschlußstutzen herausragt und daß zur mechanischen und elektrischen Verbindung des Kabelendes bzw. des Kabelschirmes mit dem Anschlußstutzen ein an der Innenseite mit elektrisch leitfähigem Klebstoff ausgebildetes Schrumpfschlauchstück vorgesehen und derart an dem Kabel angeordnet ist, daß es mit seinen endseitigen Abschnitten den Anschlußstutzen bzw. den Kabelmantel und mit einem mittleren Abschnitt den freigelegten Kabelschirm umfaßt.This task is performed with a cable connector of the type mentioned Art solved according to the invention in that the two opposite sides of the housing essentially of the two inclined surfaces arranged like a roof are formed and a connecting piece from an inclined surface protrudes that the cable with one end at which the Cable shield is freed from the cable sheath, as far as in the connecting piece is introduced that a portion of the exposed Cable shield protrudes from the connector and that for mechanical and electrical connection of the cable end or the cable shield with the connector on the Inside made with electrically conductive adhesive Shrink tube piece provided and arranged in this way on the cable is that it has the end sections Connection piece or the cable jacket and with a medium Section includes the exposed cable shield.

Bei einem derartigen Kabelstecker wird durch die dachartig zueinander angeordneten Schrägflächen und durch den an einer Schrägfläche vorgesehenen Kabelanschluß eine abgewinkelte Bauform mit einer niedrigen Bauhöhe des Steckergehäuses erreicht. Da der Kabelanschluß ohne starre Verbindungselemente, wie zum Beispiel Verschraubungen, Crimphülsen, Kabelklemmen oder dergleichen lediglich mittels eines speziellen Schrumpfschlauchstückes realisiert ist, wird auch im engeren Bereich des Kabelanschlusses wenig Einbauhöhe benötigt. Ein Kabel kann daher eng abgewinkelt, das heißt eng mit einem zulässigen Radius zu dem Anschluß hin- bzw. von diesem weggeführt werden. Aufgrund der im wesentlichen von den dachartigen Schrägflächen gebildeten Seiten eines Steckergehäuses ist diese enge Kabelführung auch bei nahe benachbarten Kabelsteckern möglich, da die dem jeweiligen Kabelanschluß gegenüberliegende Schrägfläche eines Steckergehäuses frei ist und somit die enge Kabelführung auch eines nahe benachbarten Kabelsteckers nicht behindert. Durch das für den Kabelanschluß verwendete Schrumpfschlauchstück wird zudem in einfacher Weise auch eine gute Kabelzugentlastung und gleichzeitig eine elektrische Verbindung zwischen dem Kabelschirm und dem Steckergehäuse erreicht. Dies stellt eine besonders kostengünstige Kabelverbindung für geschirmte Kabelstecker dar.With such a cable connector is roof-like mutually arranged inclined surfaces and by the at one Angled surface provided cable connection Design achieved with a low height of the connector housing. Since the cable connection without rigid connecting elements, such as screw connections, crimp sleeves, cable clamps or the like only by means of a special piece of shrink tubing is also realized in the narrower area of the cable connection requires little installation height. A cable can therefore be angled closely, that is, closely with an allowable Radius to or away from the connection will. Because of the essentially of the roof-like Inclined surfaces formed sides of a connector housing this tight cable routing even with nearby cable connectors possible because the opposite of the respective cable connection Inclined surface of a connector housing is free and therefore the tight cable routing of a nearby cable connector not disabled. Through that for the cable connection used piece of shrink tubing is also simple also a good cable strain relief and at the same time one electrical connection between the cable shield and the connector housing reached. This represents a particularly inexpensive one Cable connection for shielded cable plugs.

Zweckmäßigerweise ist das Steckergehäuse an zwei einander gegenüberliegenden Seiten mit seitlichen, senkrecht zur Steckrichtung abstehenden und gegeneinander versetzten Laschen ausgebildet, die mit einer Durchtrittsbohrung für eine Schraube zur Schraubbefestigung des Kabelsteckers an einem im Bereich des Gegensteckverbinders vorgesehenen Befestigungselement versehen sind. Eine derartige Anordnung von Befestigungslaschen ermöglicht eine Schraubbefestigung von besonders eng benachbarten Kabelsteckern.The connector housing is expediently on two opposite one another Sides with lateral, perpendicular to the direction of insertion protruding and offset tabs trained with a through hole for a Screw to screw the cable connector to an im Area of the mating connector provided fastener are provided. Such an arrangement of mounting tabs enables screw fastening of special closely adjacent cable connectors.

Im Hinblick auf die elektromagnetische Abschirmung des Kabelsteckers ist es vorteilhaft, wenn das Steckergehäuse an einer an einer Unterlage, z. B. an einer Baugruppen - oder Gerätefrontplatte anliegenden Seite mit einem auf den Gegensteckverbinder aufsteckbaren rahmenartigen Leistenkörper für die Steckkontakte ausgebildet ist. Auf diese Weise sind auch die Steckkontakte des Kabelsteckers im Bereich der Verbindung mit dem Gegensteckverbinder zuverlässig abgeschirmt. With regard to the electromagnetic shielding of the cable connector it is advantageous if the connector housing on a on a pad, e.g. B. on an assembly or device front panel adjacent side with one on the mating connector clip-on frame-like molding for the Plug contacts is formed. That is how they are Plug contacts of the cable plug in the area of the connection with reliably shielded the mating connector.

Ferner kann es in Fällen, in denen ein Kontaktgehäuse oder mehrere Kontaktgehäuse des Kabelsteckers mit Steckkontakten bestückt sind, die verschiedene Signalzweige bilden, vorteilhaft sein, wenn der rahmenartige Leistenkörper an zwei einander gegenüberliegenden Seitenflächen mit jeweils einer in Steckrichtung verlaufenden, zur Steckseite hin offenen Ausnehmung versehen ist. In diesem Fall kann eine zum Beispiel beidseitig leitend ausgebildete Baugruppe in die Ausnehmungen des rahmenartigen Leistenkörpers zwischen die Steckkontakte verschiedener Signalzweige geführt werden und diese Steckkontakte dann gegeneinander abschirmen.It can also be used in cases where a contact housing or Several contact housings of the cable connector with plug contacts are equipped, which form different signal branches, advantageous be when the frame-like inguinal body at two each other opposite side faces each with one in Recess extending direction, open towards the mating side is provided. In this case, for example assembly formed on both sides into the recesses of the frame-like strip body between the plug contacts different signal branches and these plug contacts then shield each other.

Weitere vorteilhafte Ausgestaltungen des Gegenstandes des Anspruchs 1 sind in den übrigen Unteransprüchen angegeben.Further advantageous embodiments of the subject matter of the claim 1 are specified in the remaining subclaims.

Der Kabelstecker 1 umfaßt ein Steckergehäuse 2, das aus zwei leitenden oder leitend ausgebildeten Teilen, zum Beispiel aus Metall oder metallisiertem Kunststoff, besteht. Die beiden Teile des Steckergehäuses 2 können von Halbschalen gebildet werden oder - wie bei der Ausführungsform in Figur 1 - aus einem Hohlteil 3 als Grundkörper mit aufgesetztem Deckel 4 bestehen. Das Steckergehäuse 2 enthält mehrere Kontaktgehäuse 5 (Figur 2, 3), die aus Isoliermaterial bestehen und bei der Ausführungsform in den Figuren 2 und 3 zum Beispiel von einzelnen aufeinander gestapelt im Steckergehäuse montierten Lamellenmodulen gebildet sind. Die Kontaktgehäuse 5 weisen eine Vielzahl von vorbestückten Steckkontakten 6 auf, welche einerseits lamellenweise mit den Adern 7 eines Kabels 8 verbunden sind und andererseits Kontaktelemente, zum Beispiel messer- bzw. stiftförmige oder buchsenförmige Kontaktelemente bilden, die in komplementäre Kontaktelemente eines Gegensteckverbinders 9, zum Beispiel einer Federleiste, einsteckbar sind. Das Steckergehäuse 2 umfaßt bei der Ausführungsform in Figur 1 im wesentlichen zwei Bereiche, nämlich einen anschlußseitigen Gehäusebereich 10 für den Anschluß des Kabels 8 und die Aufnahme der Kontaktgehäuse 5 sowie einen steckseitigen Gehäusebereich 11, ebenfalls für die Aufnahme der Kontaktgehäuse 5 und der Steckkontakte 6 sowie für die Steckverbindung mit einem Gegensteckverbinder. Der anschlußseitige Gehäusebereich 10 besteht aus einem Körper, der im wesentlichen von zwei dachartig zueinander angeordneten Schrägflächen 12 und 13, die von kurzen, hier zueinander parallelen Seitenflächen 14 und 15 ausgehen, und zwei der Körperform angepaßten Flachseiten gebildet wird. Dabei kann die dem Betrachter der Figur 1 zugewandte Flachseite des Steckergehäuses 2 von dem zum Beispiel schraubbar am Grundkörper befestigten Deckel 4 gebildet sein. Eine der beiden Schrägflächen des anschlußseitigen Gehäusebereiches 10, hier die Schrägfläche 12, ist mit einem buchsenförmigen Anschlußstutzen 16 ausgebildet, der hier im rechten Winkel von dieser Schrägfläche abragt und etwa mittig oder im Dachfirstbereich" des anschlußseitigen Gehäusebereiches 10 angeordnet ist. Der Anschlußstutzen 16 dient der Einführung und dem Anschluß eines vieladrigen Kabels 8, welches an seinem anzuschließenden Ende auf einer bestimmten Länge vom Kabelmantel 17 befreit ist. Das Kabelende ist soweit in den Anschlußstutzen 16 eingeführt, daß ein Teilbereich des freigelegten Kabelschirmes 18 aus dem Anschlußstutzen 16 herausragt. Zur mechanischen und elektrischen Verbindung des Kabelendes bzw. des Kabelschirmes 18 mit dem Anschlußstutzen 16 des Steckergehäuses 2 ist als einziges Verbindungselement ein Schrumpfschlauchstück 19 vorgesehen, das an seiner Innenseite mit elektrisch leitfähigem Klebstoff ausgebildet ist. Das Schrumpfschlauchstück 19 ist dabei derart an dem Kabelende angeordnet, daß es mit seinen endseitigen Abschnitten 20, 21 den Kabelmantel 17 bzw. den Anschlußstutzen 16 und mit einem mittleren Abschnitt 22 den freigelegten Kabelschirm 18 umfaßt, wobei bei unter Wärmeeinwirkung auf das Kabelende aufgeschrumpftem Schrumpfschlauchstück 19 im mittleren Abschnitt 22 eine Einschnürung 23 gebildet ist. Wie die Figur 2 deutlich zeigt, ist der Innendurchmesser des Anschlußstutzens 16 im Hinblick auf einen zuverlässigen Kabelanschluß zweckmäßigerweise an den Kabeldurchmesser im Bereich des freigelegten Kabelschirmes 18 angepaßt.The cable connector 1 comprises a connector housing 2, which consists of two conductive or conductive parts, for example made of metal or metallized plastic. The two parts of the connector housing 2 can be formed by half shells or - as in the embodiment in FIG. The connector housing 2 contains a plurality of contact housings 5 (FIGS. 2, 3), which consist of insulating material and, for example, in the embodiment in FIGS. 2 and 3 are formed by individual lamella modules stacked one on top of the other in the connector housing. The contact housings 5 have a large number of pre-fitted plug contacts 6, which are connected on the one hand in lamellae to the wires 7 of a cable 8 and on the other hand form contact elements, for example knife-shaped or pin-shaped or socket-shaped contact elements, which form complementary contact elements of a mating connector 9, for example a female connector, can be inserted. In the embodiment in FIG. 1, the plug housing 2 essentially comprises two regions, namely a housing region 10 on the connection side for connecting the cable 8 and receiving the contact housing 5 and a housing region 11 on the plug side, likewise for receiving the contact housing 5 and the plug contacts 6 and for the plug connection with a mating connector. The connection-side housing area 10 consists of a body which is essentially formed by two roof-like inclined surfaces 12 and 13, which start from short, here parallel side surfaces 14 and 15, and two flat sides adapted to the body shape. In this case, the flat side of the plug housing 2 facing the viewer of FIG. 1 can be formed by the cover 4, for example screwed to the base body. One of the two inclined surfaces of the connection-side housing area 10, here the inclined surface 12, is formed with a socket-shaped connecting piece 16, which projects here at a right angle from this inclined surface and approximately in the middle or in Roof ridge area "of the connection-side housing area 10 is arranged. The connection piece 16 serves for the introduction and connection of a multi-core cable 8, which is free from the cable sheath 17 at its end to be connected. The cable end is inserted into the connection piece 16 so far that a Part of the exposed cable shield 18 protrudes from the connector 16. For the mechanical and electrical connection of the cable end or the cable shield 18 to the connector 16 of the connector housing 2, the only connecting element provided is a piece of shrink tubing 19 which is formed on the inside with electrically conductive adhesive. The shrink tube piece 19 is arranged at the cable end in such a way that it comprises the cable sheath 17 or the connecting piece 16 with its end sections 20, 21 and the exposed cable shield 18 with a central section 22, with under heat a constriction 23 is formed in the middle section 22 due to the shrunk-on shrink tube piece 19 shrunk onto the cable end. As FIG. 2 clearly shows, the inner diameter of the connecting piece 16 is expediently adapted to the cable diameter in the region of the exposed cable shield 18 with a view to a reliable cable connection.

Ferner ist das Steckergehäuse 2 des Kabelsteckers 1 an einer an einer Unterlage 24 anliegenden Unterseite 25 des anschlußseitigen Gehäusebereiches 10 mit einem auf den Gegensteckverbinder 9 aufsteckbaren rahmenartigen Leistenkörper 26 für die Steckkontakte 6 ausgebildet. Dieser Leistenkörper 26 ist bei der dargestellten Ausführungsform an zwei einander gegenüberliegenden Seitenflächen 27, 28 mit jeweils einer in Steckrichtung verlaufenden, zur Steckseite hin offenen Ausnehmung 29 bzw. 30 versehen. Die zueinander fluchtend angeordneten Ausnehmungen 29, 30 befinden sich damit genau in Höhe eines Zwischenraumes, der zwischen jeweils zwei parallelen Reihen 31 und 32 von Steckkontakten 6 gebildet ist, die hier zwei gegeneinander abzuschirmende Signalzweige bilden. Fluchtend zu den Ausnehmungen 29, 30 sind hier - wie insbesondere die Figur 3 zeigt - die Kontaktgehäuse 5 steckseitig ebenfalls mit einer Ausnehmung 33 versehen, so daß in die Ausnehmungen 29, 30 des Leistenkörpers 26 und in die Ausnehmung 33 der Kontaktgehäuse 5 eine beidseitig leitend beschichtete Baugruppe 34 zur Abschirmung der beiden Signalzweige gegeneinander eingeführt werden kann. Bei der dargestellten Ausführungsform nach Figur 3 ist auf jeder Seite der Baugruppe 34 jeweils ein Gegensteckverbinder 9, zum Beispiel eine Federleiste, beispielsweise in SMD-Technik, angebracht, wobei die Gegensteckverbinder 9 eine hochpolige, geschirmte Steckverbindung mit einem Kabelstecker 1 bilden. Bei einer wie in Figur 3 dargestellten Anordnung wird die Hochpoligkeit durch kleine Rasterabstände (bis 1 mm) erreicht, wobei bei Bedarf an Abschirmung Zwischenkontakte an Masse gelegt werden können. In diesem Fall ist dann zum Beispiel jede zweite Spalte von Steckkontakten 6 kein Signalzweig, sondern sie wird an Masse gelegt, wobei die entsprechenden Kontaktelemente des Gegensteckverbinders dann ebenfalls Massekontakte sind.Furthermore, the connector housing 2 of the cable connector 1 is on one on a base 24 adjacent bottom 25 of the connection side Housing area 10 with one on the mating connector 9 clip-on frame-like strip body 26 for the Plug contacts 6 formed. This last body 26 is at the illustrated embodiment on two opposite Side surfaces 27, 28 each with one in the direction of insertion running, open to the mating side recess 29 or 30 provided. The aligned with each other Recesses 29, 30 are thus exactly in the amount of one Space between two parallel rows 31 and 32 is formed by plug contacts 6, here two form signal branches to be shielded from one another. Aligned to the recesses 29, 30 are here - such as in particular Figure 3 shows - the contact housing 5 also on the plug side provided with a recess 33 so that in the recesses 29, 30 of the last body 26 and in the recess 33 of the Contact housing 5 an assembly coated on both sides 34 to shield the two signal branches from one another can be introduced. In the illustrated embodiment 3 is on each side of the assembly 34th each a mating connector 9, for example a female connector, for example, in SMD technology, where the Mating connector 9 a multi-pin, shielded connector Form with a cable connector 1. With one like in figure 3 arrangement is shown by the high polarity small grid spacings (up to 1 mm) achieved, if necessary Intermediate contacts can be connected to ground on the shield. In this case, for example, every second column of plug contacts 6 no signal branch, but it is on Ground, the corresponding contact elements of the Mating connector are then also ground contacts.

Diese Befestigungselemente 38 bestehen zum Beispiel aus einer Hülse mit Innengewinde, einer Mutter oder einem Blechwinkel mit Gewindedüse, wobei für die Befestigung eines Kabelsteckers jeweils zwei Befestigungselemente 38 beidseitig eines Gegensteckverbinders 9 auf der Baugruppe 34 montiert sind. Auf diese Weise können Steckergehäuse von Kabelsteckern eng benachbart mit der zwischen den Laschen 35 und den Befestigungselementen 38 liegenden Frontplatte 24 kontaktiert werden. Die in Figur 2 dargestellte Steckverbindung läßt sich durch die vorteilhafte Ausbildung des Steckergehäuses der Kabelstecker und der Kabelanschlüsse bei engen Einbaubedingungen mit einer Bauhöhe H von nur etwa 40 mm inklusive Frontplatte 24 realisieren. To attach a cable connector 1 to the base, for Example on the front plate 24 of the assembly 34 is the connection side Housing area 10 of the connector housing 2 at its opposite short side surfaces 14 and 15 formed with side tabs 35 which are perpendicular to Stick out and staggered are and also each with a through hole 36 for a screw 37 are provided, which for screw fastening of the cable connector 1 in the area of the mating connector 9 provided fasteners 38 serve. These fasteners 38 consist for example of a sleeve with Internal thread, a nut or a sheet metal bracket with threaded nozzle, being for attaching a cable connector each two fastening elements 38 on both sides of a mating connector 9 are mounted on the assembly 34. In this way can be closely adjacent to connector housings of cable plugs the between the tabs 35 and the fasteners 38th lying front plate 24 can be contacted. The in Figure 2 The connector shown can be advantageous Formation of the connector housing of the cable connector and the cable connections in narrow installation conditions with a height H of only about 40 mm including front plate 24.
